Abstract
Borophene has been gaining much attention due to its potential applications in quantum optics technology. In this study, an absorption model, which depends on the polarization of the incident beams, has been developed. This model shows that the coherent absorption in borophene monolayers (stripped, β12, χ3) can be modulated across a wide range of frequencies, and coherent perfect absorption can be achieved in p and s polarization. The absorber can achieve such control without changing its properties by adjusting the incident beam polarization. Stripped borophene can absorb 90% of incident beams across an ultra-wide bandwidth of 40 THz. These findings present a new method for creating adaptive borophene-based absorbers with a high absorption bandwidth, and can be implemented as optical sensosrs.
